BASstat221 – BACnet Communicating for Multi-Stage Heating/Cooling

The BASstat series of BACnet-compliant wired or wireless communicating are BTL listed to ensure ef- fortless integration into BACnet/IP (Wi-Fi) or BACnet MS/TP (EIA-485) networks. These thermostats are suited for single or multi-stage heating, cooling and ventilation binary out- put control applications such as RTU or AHU. Configurable control algorithm parameters allow adaptability to the Wi-Fi specific application. Adaptive control algorithm applied to multi-stage on/off control saves energy and ensures seam- less comfort for the occupants. Built in temperature sensor, input for remote temperature sensor, or temperature over- ride network command from System. A built-in relative sensor (in 221CH models) allows the thermostat to display relative humidity on the screen as well as serve it as a BACnet object, dew point calculation is also served as a BACnet object (no control action is taken • Occupied / Unoccupied modes with 2 sets of based on humidity).

BASstat – Overview The BASstat’s white backlit LCD display is large and easy Six buttons on the BASstat allow users to manipulate to read, even from a distance. It incorporates graphical temperature set point, change HVAC modes, turn the icons to aid visual indication of current state of operation. thermostat ON/OFF, and more. Pressing the Set and Up/ Several icons indicate parameters such as: Active Mode, Down buttons can manually toggle the thermostat from Cooling stage 1 or 2, Heating stage 1 or 2, Ventilation Only, occupied/unoccupied modes, where BACnet occupancy Active, Occupied / Unoccupied state, and Clock icon command is not an option. All 6 of these buttons are lock- to indicate Short Cycle Delay or Max Cycles per hour active able in a configurable manner to prevent unauthorized waiting state. These icons are very useful in indicating the configuration change. Some or all buttons can be locked thermostat’s current state of operation. for application flexibility, making the stat suitable for ap- plications where limited user control is allowed.
